[PATCH] D24414: Conditionally eliminate library calls where the result value is not used

[Rong Xu via llvm-commits]

Move internal option -disable-libcalls-shrinkwrap to PassBuilderManager per
Mehdi's suggestion. Also check the FP format. This is primarily for long double
type where the powerpc has narrower range than in x86. We only handle
x87DoubleExtended format for long double for now.
